Road traffic should continue to lighten into the evening, leading up to the many road closures for tomorrow’s AJC Peachtree Road Race.

Preparations for the Peachtree have already prompted road closures downtown. Tenth Street between Charles Allen and Monroe drives has been closed since 9:30 a.m. Monday and will remain closed through 5 p.m. Wednesday. 

For any night owls out there, many other roads will be closed starting at 4:30 a.m.

It reached at toasty 91 degrees in Atlanta Tuesday, and that’s expected to continue Wednesday afternoon, Channel 2 Action News meteorologist Brian Monahan said.

Luckily for racers, the predicted high of 90 degrees will come in the afternoon, and temperatures should remain in the 70s and low 80s during the morning.

Channel 2 Action News Chief meteorologist Glenn Burns said it will be humid though, reaching up to 90 percent by 6 a.m. The humidity will lighten up slightly as the morning progresses but not by much, he said.

However, there is a chance of an isolated morning shower Wednesday, according to Monahan.

“Tomorrow morning, 6 a.m., just before the start of the race, a couple of showers will be around,” Monahan said. “I can’t rule out a isolated shower for the Peachtree tomorrow morning, but overall that rain chance is pretty low. As we head through your July 4 afternoon, some isolated showers and storms developing.”

It should be mainly dry by fireworks time, after the sun goes down. Wednesday’s rain chance is slight for the morning and 40 percent for the afternoon, and high temperatures should be in the upper 80s, according to Channel 2. 

“I expect the highest coverage of rain to stay mainly south of I-20,” Monahan said.
